'1931. Serial No. 527,903. 1 l K I The invention is a completely sealedenclosure atthe front of ,a furnace which encloses the ends of the grates, shaker bars and ash pan and forms anauxiliary housing providing a double check to preventashessifting out of the front of thefurnace. I

This application is va divisionfrom my prior copendingapplication fora patent for I p a furnace grate which was.fil'ed'JulyQ, 1928,

with theSerial Number 291330, the former being now restricted to the grate.

The object of the invention is to provide a furnace in which the lower part "of the front is completely enclosedto prevent dust 1.1 from the ashes dropping from the grate to the ash pan escaping. Another object of the inventionis'to provide a furnace front having a narrow horizontal opening through which the grate bars may readily be removed. I

A further object of the invention isto provide'an auxiliary'furnace front which may be used with any typeof furnace.

And a still further object of the invention is to provide an auxiliary furnace front forenclosing the grate ends andashpanwhich is of a simpleand economical construction. With these ends in view the invention embodies a housing adapted to be attached to F the lower portion of a furnace front, a plate. forming the lower part of the front with,

grate and ash pan openings therein, another plate forming aclosure for the ings, and an upper and lower oor in the housing with a damper in the lower door.

Other features and advantages of the in vention will appear from the following de: scription taken in connection with the drawings, wherein stalled at the front of a furnace. A

Figure 2 is a crosssection through the housing looking toward the furnace with part broken away. 3 Figure 3 is a cross sectionthrough the housing and lower part of the furnace front taken atright angles to that shown in Fig: ure 2.

Figure 4 is a View showingthe grate openate open Figure 1 is aview showing the housing in- 'hasran opening 23 which is covered b y a In the drawings the furnace front is shown as it would ,be made wherein numeral 1 indi and replaced, and also a lower opening 9 for the ash pan which'is indicated by'the'numeral 10., The upper edge ofthe portion 5 is providedwith two semicircular openings 11 and 12 in'which the ends 13 of thegrate bars rest as shown. I A plate 3 is provided to cover the opening-S and.;.this is heldin a clip .14 on the j plate 5. Openings 15 are provided in the lower edge of the plate 3 to fit over the ends 13 of the grates and. smaller openings 16 areprovided to fit over thumb screws 17 ,in the* plate 5 and clip 14: which may be screwed ins ward to bind and hold the plate in place. It will be noted that this plate fits snugly :over the ends. of the grates and completely seals. the opening Sthroughwhich the grates pass.

A knob-18 is" provided atv theupper edge of the plateby which it maybe held when re moving or replacing. The upper edge of the plate may be straight as shown in Figure 2 or bent over as shown in Figure 31asmay be desired. i

The housingQ is of a rectangular shape withan upper door '19 and a lower .door 20 at the front and both of the doors are hinged to the housing at the point 21 and arranged in such a manner that when open'the entire front ofthe housing will. be open to permit. the grate bars and ash pan 'to be removed I and replaced therethrough. Both doorsare provided with knobs'22 and the lower door 7 smaller, door 24: and the, door 24 hasa damper 25.. The door 24sis pivotally inountedon a horizontal pin 26 which is supported in bear- I ings 27' at the upper edge ofthe door 20 and it will be noted that it will normally hang other may be in the use of doors of a different typeor design at the front of the housing.

The construction will be readily under stood from the foregoing description. In use the front of the furnace and the housing may be provided and installed as shown and it will be observed that when it is desired to shake the grate or remove the clinkers therefrom it is only necessary to open the upper door and when it is desired to remove the ash pan it is only necessary to open the lower door. This device provides a double check front having horizontal openings providing passage for the rate bars and ash pan, a removable plate orming a closure for said grate bar opening, means for holding said removable plate, a box like housing forming an enclosure for the lower part of said furnaoe front and covering said grate and ash pan openings, doors at the outer end of said enclosure, a smaller door covering an openingin one of said enclosure doors, and a damper in said smaller door.

In testimony whereof I aflix my signature.

on the ashes sifting through and out into i the room as the furnace front 1 is practically sealed so that very few ashes will sift through into the compartment 2, and as there are very few ashes in this compartment there will not be much chance of them escaping out into the room. At the same time this construction makes it possible to readily remove and replace the grate bars without tearing down or injuring any part ofthe furnace.

Having thus fully described the invention what I claim as new and desire to secure by Letters Patent, is:

-1.- In a furnace front of the type having a flat plate forming the front of the furnace with grates having shaker ends extending through the-plate and an ashpan under the grate, said front plate having horizontal openings providing passage for the said grates and ash pan, a readily removable plate orming a closure for the grate opening, said plate having slots fitting over the grate ends,

clamping members for holding1 said plate, a

complete housing enclosing t e lower portion of said furnace front and covering said grate and ash pan openings, doors at. the outer end of said housing making it possible to open the entire area thereof, a smaller door hinged'on one of the said housing doors and covering an opening therein, and a damper in said smaller door.

2. In a furnace of the type having shaker grates and an .ash pan, a plate forming the furnace front having horizontal openings for the grate bars and ash pan, a closure for the said grate bar opening, a box like housing enclosing the lower portion of said furnace front, doors at the outer end of said housing,

and a dam er in one of the said doors.
